Abstract: An in-band pseudolite wireless positioning method, system and device are provided. The system has a base station, a pseudolite and a terminal. The base station transmits identifier information to the pseudolite after correcting a transmission clock of the pseudolite and transmits a pseudolite array and positioning correction information to the terminal. The pseudolite generates a random positioning signal sequence according to the identifier information and transmits a positioning signal according to the transmission clock and the random positioning signal sequence. The terminal generates a random positioning signal sequence of the pseudolite according to the pseudolite array and the positioning correction information. The terminal further matches the received positioning signal according to the random positioning signal sequence to obtain the arrival time of the positioning signal and obtain through calculation the position coordinates of the terminal according to the position coordinates of the pseudolite and the arrival time.
